In a UK laboratory, researchers are exploring the potential of a “solid refrigerant” that may transform the air-conditioning industry by eliminating the need for harmful greenhouse gases. This soft, waxy substance may not seem impressive at first glance, but its properties are truly groundbreaking. Unlike traditional gases, the temperature of this solid refrigerant can fluctuate by more than 50 degrees Celsius under pressure, offering a more energy-efficient and environmentally friendly alternative.
Professor Xavier Moya, leading the research at the University of Cambridge, has been studying these plastic crystals for over 15 years. These crystals, composed of rotating molecules, exhibit the “barocaloric effect” where they cool the surroundings when released from pressure. The potential applications of this technology are vast, with the ability to significantly reduce emissions associated with air-conditioning units worldwide.
Barocal, a startup founded by Moya in 2019, aims to commercialize these research findings and bring innovative cooling products to the market. With investments from organizations like the European Innovation Council and Breakthrough Energy, the startup is making strides towards developing efficient cooling units that could reduce emissions by up to 75%. While the current prototypes are still in the optimization phase, Barocal is confident that they will soon rival traditional gas-powered units in terms of performance.
The company plans to launch its first product within three years, targeting commercial spaces like shopping centers, schools, and data centers. By offering the promise of cheaper bills in the long run, Barocal hopes to convince businesses to adopt their technology. Ultimately, the goal is to make these cooling units accessible to residential consumers at prices comparable to traditional units. With the potential to revolutionize the air-conditioning industry, Barocal’s solid refrigerant technology holds promise for a greener and more energy-efficient future.
